The latest planting time of leek

Leek leaves, flower scape and flowers are eaten as vegetables, seeds and so on can be used as medicine, with kidney, stomach, refreshing, antiperspirant astringent and other effects, leek adaptability, cold and heat resistance, all over the country have cultivation, let's take a look at leek planting time and planting conditions!

leek planting time

The sowing time of leek can be divided into three kinds: spring sowing, summer sowing and autumn sowing:

1, spring sowing: early not late, spring when the ground temperature is stable at 5-10℃ can be sown, at this time the ground has not been completely through, return to the pulp period has not reached the surface is relatively wet, it is easy to emerge, this sowing method also avoids grass damage, due to the rapid emergence of leek seedlings after sowing, and the temperature at that time is not suitable for weed germination, forming a time difference. Therefore, it is recommended that everyone try to use this method of sowing.

2, summer sowing: generally in cucumber, tomato strike garden after sowing, at this time the temperature is high prone to drought and waterlogging, sowing amount is about one-third larger than spring, soil is not too thick, keep the soil moist, conducive to the full seedlings.

3, autumn sowing: generally in the beginning of autumn before and after sowing, sowing quantity should be twice as large as spring, management to see dry see wet mainly. Later attention should be paid to grass damage. Autumn sowing is generally not encouraged.

leek cultivation conditions

Leek belongs to perennial root vegetables of lily family, with strong adaptability, cold and heat resistance. It is cultivated everywhere in China. Many areas in the south can produce all the year round. Although the aboveground part of the north dies in winter, the underground part enters dormancy, and the topsoil germinates and grows after thawing in spring.

1, temperature: chives like cold, cold and heat resistance, seed germination temperature is above 12℃, growth temperature 15℃ to 25℃, underground part of the tolerance of lower temperatures.

2, light: moderate light intensity, strong negative resistance. But the light is too weak, the accumulation of photosynthetic products is less, the tillers are few and thin, the yield is low, and the premature senescence is easy; the light is too strong, the temperature is too high, the fiber is too much, and the quality is poor.

3, moisture: suitable air relative humidity 60-70%, soil moisture for the field maximum water capacity of 80-90%.

4. Soil: leek has strong adaptability to soil texture, and the suitable pH is 5.5-6.5. Fertilizer needs large, strong ability to tolerate fertilizer.

Chinese chive variety classification

Chinese chives are very rich in variety resources. According to edible parts, they can be divided into four types: root chives, leaf chives, flower chives and leaf chives.

1. Root Allium: Root Allium is mainly distributed in Yunnan, Guizhou, Sichuan, Xizang and other places in China. It is also known as Allium, Allium latifolia, Allium macrophyllum, Mountain Allium, Chicken Foot Allium, etc. Mainly edible root and flower bolt. Rooted robust, fleshy, spicy flavor, can be processed pickled or cooked. Flower sprouts fat tender, can be fried food, tender leaves can also be eaten. Root chives to asexual reproduction mainly, tillering power, growth potential prosperous, easy to cultivate. The main harvest in autumn.

2. Leaf Allium: The leaves of leaf Allium are thick and soft, and the bolting rate is low. Although it can also bolt for food at the reproductive growth stage, it mainly uses leaves and leaf sheaths for food. It is cultivated everywhere in our country. This type is mainly used in softening cultivation.

3. Flower Allium: Flower Allium is specially used to harvest the flower sprouts of leek for food. Its leaves are short, thick and hard in texture, strong in tillering and high in bolting rate. Flower sprouts high and thick, crisp quality, similar to garlic sprouts, especially the United States flavor. Lan 'Zhou City and Taiwan Province of Gansu Province are cultivated more frequently. Shandong and other places also have sporadic introduction cultivation. There are many varieties of Chinese chives, such as small leaf species: bolting and tillering strong, narrow and short leaves, thick color, thin and slightly green leaf sheath, leaf and leaf sheath quality is hard, early maturity, leaf and flower dual use, medium quality; annual Chinese chives: bolting strong, flower stem long, leaf width medium and long, thick green, leaf sheath large, slightly yellow red. Leaf and leaf sheath are hard, bolting period is long, annual bolting can be done, leaves are not suitable for eating, mainly bolting; Nianhua No. 2: thick flower stem, good quality, low temperature tolerance.

4. Leaf-flower Allium: The leaves and flower bolts of Leaf-flower Allium are well developed and can be eaten. At present, most of the leek varieties cultivated in China are of this type. This type can also be used for softening cultivation.
